These two popular varieties of peppers are both considered to be ‘hot’ peppers, but they have their own distinct flavor and characteristics. But what’s the difference between a Fresno pepper and a jalapeno pepper? Which one is right for you and your dish?
In this guide we’ll provide an in-depth comparison between the two types of chile peppers as well as a taste-test so that you can make the best decision when it comes time to choose which kind will top off your meal!
What is Fresno?

Fresno peppers are a type of mild-heat pepper that is related to the jalapeno. It has an overall fresh flavor, with a hint of sweetness and subtle hints of smokiness. Its thick walls make it best for grilling or roasting, as opposed to being eaten raw.
Fresno peppers range from green to red in color and measure about two inches in length. They are generally seedier than jalapenos, although this varies depending on the exact variety.
What is Jalapeno?

Jalapeño peppers are slightly hotter than Fresno chilies and have thin walls that make them ideal for slicing and eating raw or cooking quickly over heat. These chilies come in both red and green varieties and range from 2 to 4 inches in length. Jalapeños have a bold flavor with hints of citrus, grassiness, and a moderate amount of heat that can range from mild to hot depending on the variety.
